Organic tea has a simple and traditional flavor which is probably the same as teas grown many years ago in ancient Japan. And organic tea more directly brings the antecedents in the flavor than non-organic tea. The antecedents are the features of breed, soil, climate, and efforts by the farmer.
Therefore the flavor of organic Japanese tea is quite affected by these efforts, climate and soil. To grow high grade and quality organic tea, it is required to meet some terms, which are (1) extra time and effort, (2) the range of temperature between day and night in the rolling hills, and (3) calcareous earth. There are not so many places even in Japan which are perfect for farming high quality organic tea.
Generally, it is said that high grade and quality gyokuro and matcha need much fertilizer. It is not easy to grow high grade and quality organic gyokuro and organic matcha because organic fertilizer works slowly. (In contrast chemical fertilizer works quickly and efficiently in about a month and organic fertilizer works slowly for 3 to 9 months.)
When a lot of time and effort is put into the growing of organic tea, the tea flavor can become truly excellent. (eg. our Organic Gyokuro, Organic Sencha Premium, Organic Matcha etc.) However, unfortunately such excellent grade and quality organic tea is rare, because most organic farmers think that growing such high grade organic tea will not bring farmers economic success, but just require a lot of time and effort. Most tea farmers in Japan grow low to middle grade organic teas.
And as above, organic fertilizer works slowly. So, organic tea trees are more of a burden than non-organic tea trees. To put it the other way around, chemical fertilizer in non-organic tea farms makes the growing process much more easy. From the perspective of modern cultivation, it can be said that it produced considerable improvement of traditional cultivation and brought the tea industry amazingly high productivity. It is definitely one of the contributions of modern agriculture.

Many of our tea farms have ideally calcareous earth. Fossils used to be dug up near our tea farms.
